Hello!

I definitely agree with all the words written below and I would like to add
few wishes.

I am interested in industrial devices communicating by fieldbuses. I use
the NuttX port of FreeModbus stack and I would like to see more port of
communication stacks like this. I prefer CANopen and Profinet, There are
several open source communication stack for these protocols.

Thank you and have a nice day.
